Reconstruction Of The Tool Of TTCN-3Test Suite Automatic Generation Based On GFT

With the continuous development of computer software technology, more and more people attach great importance to the quality of software products. And software testing is to improve software quality protection. The automated software testing technology and tools is an important way of promoting the development of software testing applications. Automated testing tools can effectively improve the software testing process. It has the characteristics of repeatability, easy operability, reliability and so on. So the software can be efficiently tested and reducing the test time in the implementation process, human and hardware resources consumption. Thus it improved software testing high cost and low efficiency situation.TTCN-3(Testing and Test Control Notation version3) is a powerful test description language. It has a wide range of applications and development prospects. As an international standard test language, it is provided with the complete theoretical foundation to achieve automated testing tools. It has a variety of presentation format, where GFT (the Graphical presentation Format of TTCN-3) is TTCN-3graphical representation designed for intuitive and clear description of the purpose of testing. At present, less domestic support for TTCN-3test automation tool and provides a graphical editing tool is still in the exploratory stage.The subject on the basis of support for TTCN-3test automation platform TTRun which is research and development by North China University of Technology of Software Architecture Laboratory. In support of graphical representation of the format to improve the test suite of visualization and development efficiency, Reconstruction the platform TTRun original TTShow.The main content of the subject is according to TTCN-3test sets of characteristics on GFT expansion. The GFT expansion can effectively describe the standard GFT specification can not be described in TTCN-3module definitions part and GFT TTCN-3module tiered management support GFT Figure reuse. According the eclipse plug-in development technology to achieve the GFT extended editor and Optimization the TTShow instruments provided GFT diagram editor. It achieve GFT graph transformation to generate TTCN-3core language represented by the test suite algorithm. Process this subject to achieve TTCN-3test suite tools automatically generate and it have support GFT diagram editor and easy to operate and reuse. The tool integration reconstructed TTShow to TTRun platform to improve the platform TTRun test suite development efficiency and support test suite of visualization.By the last, through two actual test case, use test sets automatically generated tools to diagram editor and automatic generation of test sets. By the TTRun provided TTCN-3text editor to automatically generated test suite for parsing and compilation process. View log information to validate the graphics conversion code feasibility and tools practicality.
